Exchanging Sketchpad Files Over the Net

Annie and whoever,

I would love to see the Sketchpad sketches that students in Keith's
classes are producing not to mention interesting ones from other people.
I would also be happy to share some of my own. For example, I have
Sketch with my solution to the maximum-goal-angle hockey problem (posted
earlier) that documents the discovery process I went through, that is,
what conjectures I made initially, and found to be false, before finding
one that worked. I also have Sketches for potential solutions for the
dog-pen problem (also posted earlier), an elevator door mechanism
simulation, a dynamic illustration of trig functions, ...

The question is: Is there a format (e.g., BinHex) that we can all use
and agree on to exchange Sketches? As a fringe benefit doing this could
also be useful for posting files from other non-text software (e.g., MS
Word, MacDraw, ...).

I've been using the Macintosh Desk Accessory (DA) called BinHqx 1.0 for
this purpose. It's available as ShareWare (I just sent off my $5 to
"register" my copy).

Keith: Can you get files from your mail reader to your Mac? Do you
have the BinHqx DA or something else that can decode files encoded in
BinHex 4.0 format? Would you like to be able to do this?

Would other people be interested in the ability to exchange Sketchpad
files, etc. over the network? By the way, I've found it quite useful in
doing research collaborations to be able to send MS Word documents back
and forth across the net.
